API Integration FAQ
What does API Integration usually connect?
API Integration usually connects commerce, fulfillment, and finance systems so events move automatically instead of being re-entered manually.
Is it only a developer topic?
No. Business rules, field mapping, exception handling, and go-live testing matter as much as the code layer.
What is the main risk?
The main risk is assuming systems are connected when timing, field definitions, or owners are not aligned.
